The North Korean ballistic rocket launch on December 12 will have a negative effect on efforts to resume the six-party talks on the nuclear problem of the Korean Peninsula, Russian Foreign Ministry Special Ambassador Grigory Logvinov told Interfax on Thursday.

"The rocket launch will inevitably affect the general atmosphere in the region and the efficiency of the efforts toward providing conditions for re-launching the six-party negotiating process," Logvinov said.

He called on "all parties concerned to refrain from any actions that could lead to the worsening of the situation."

Despite the new complications, "we do not see another alternative to the six-party talks," which are "the most efficient platform" not only for resolving the nuclear problem of the Korean Peninsula but also for creating a favorable situation in the region, he said.

"It should be born in mind that the six-party talks have been granted a UN Security Council mandate," Logvinov said.
